Interoperability is the ability of two or more medical devices, products, technologies, or systems to exchange and use information with consideration for safety, effectiveness, and security. For devices, interoperability needs to be designed in: manufacturers should define the purpose of each interface, the data exchanged, the standards used (such as HL7 FHIR, DICOM or IEEE 11073) and the limits of what connected systems can safely do. FDA's 2017 guidance on interoperable medical devices recommends describing interfaces in labeling and addressing interface-related risks, including cybersecurity, in the risk analysis.

Why it matters

FDA's interoperability guidance recommends defining the purpose of an electronic interface, anticipated users, risk management, validation, and labeling.

Common pitfalls

•Ignoring cybersecurity risks associated with data exchange can lead to vulnerabilities and patient harm.
•Failing to validate interoperable systems as a whole can result in unidentified functional or safety issues.
•Assuming that all interconnected devices will seamlessly exchange data without explicit interface requirements is a common mistake.
•Neglecting to define clear use cases and expected performance for an interoperable system can lead to design flaws and regulatory non-compliance.

Why compare MedTech terms side by side?

MedTech terminology is full of pairs that look interchangeable but carry very different regulatory, clinical, and commercial consequences. Picking the wrong framework, pathway, or standard early in a project can add months to a submission, invalidate clinical evidence, or trigger an audit finding. Side-by-side comparison is the fastest way to surface those differences before they become costly mistakes.

Each comparison on this page pulls from the same vendor-neutral, sourced definitions used throughout the MedTech Terms glossary. You see the one-line summary, the formal definition, why it matters in practice, common pitfalls, and the primary sources (FDA guidance, EU MDR/IVDR articles, ISO/IEC standards, MDCG documents, IMDRF principles) that back each entry. That makes the comparison defensible in regulatory strategy memos, design reviews, and submission narratives.

Common comparison patterns

Regulatory pathway choice - 510(k) vs PMA, 510(k) vs De Novo, Abbreviated vs Special 510(k).
Quality systems - QSR vs ISO 13485, QMSR vs QSR.
Software classification - SaMD vs SiMD, Locked vs adaptive AI.
EU frameworks - MDR vs IVDR, CE Mark vs UKCA.
Cybersecurity artifacts - SPDX vs CycloneDX SBOM, CVE vs CVSS.
Post-market actions - Recall vs field action, Removal vs correction.
